[Tex/LaTex] How to make fractions in powers look good

Question

Quick question. When I type $e^{\frac{1}{2x}}$ it makes the fraction very small and hard to read. However when I type $e^{\displaystyle\frac{1}{2x}}$ it makes the fraction way to big. I guess in either case they do not look good to me. Is there a nice way to make fractions in powers look good?

Answer 1

You can also use the xfrac package which provides \sfrac which works in text and math mode:

Note:

• I stopped using \sfrac when I realized that it was resulting in really slow compiles when used in conjunction with the microtype package as per:

  • Why does the use of microtype and xfrac lead to a long compile time?
  • Disable microtype for a portion of a document

  I think these problems are supposed to have been fixed with microtype v2.5, but in case you encounter really slow compile times you may want to try it without the microtype package or without \sfrac{}.

Code:

\documentclass{article}
\usepackage{xfrac}

\begin{document}
Works in text mode \sfrac{1}{2} and in math mode $\sfrac{1}{2}$.

In exponents: $e^{\sfrac{1}{2}}$
\end{document}
